r-Process enrichment in the Galactic halo characterized by nucleosynthesis variation in the ejecta of coalescing neutron star binaries
Takuji Tsujimoto, Nobuya Nishimura, Koutarou Kyutoku
A large star-to-star variation in the abundances of r-process elements, as seen in the [Eu/Fe] ratio for Galactic halo stars, is a prominent feature that is distinguishable from ot…
Early chemical evolution of Zn driven by magnetorotational supernovae and the pathway to the solar Zn composition
Takuji Tsujimoto, Nobuya Nishimura
The site of Zn production remains an elusive and challenging problem in astrophysics. A large enhancement of the [Zn/Fe] ratios of very metal-poor stars in the Galactic halo sugges…
The r-process in Magnetorotational Supernovae
Takuji Tsujimoto, Nobuya Nishimura
One of the hottest open issues involving the evolution of r-process elements is fast enrichment in the early Universe. Clear evidence for the chemical enrichment of r-process eleme…
